    are you saying that time.wday did not work?

    $ irb
    ruby-1.8.7-p302 > time=Time.new
    => Thu Feb 02 09:11:24 +0000 2012
    ruby-1.8.7-p302 > time.wday

    What type is bill_date? Assuming it is a Time or Date object then you want
    u.bill_date.month

    date is not a class type. It could be Date. Do you mean that the

    What happens when you do bill_date.month as I suggested?

    By the way please remember to include the relevant parts of the

    Are you sure that does not give you the day of the month, I would have
    expected wday to give day of week, though since you still have not
    told use what type bill_date is then we cannot be sure.
    :day_of_month =>
    (Date.new(Time.now.year,12,31).to_date<<(12-u.bill_date.month)).day ,
    As I said above I would have expected day or mday to give the day of month

    If you get an error you have to look at it and work out what it means,
    which is not always easy but you will get better at it with practice.
    It is no good asking for help here and just saying you got some error,
    you must provide the details, but first try and understand the error.
    Also read up on and experiment with the rails console, it can be very
    useful for trying things out, for example:

    $ rails console
    Loading development environment (Rails 3.1.3)
    ruby-1.8.7-p302 > u=User.first
    User Load (0.9ms) SELECT `users`.* FROM `users` LIMIT 1
    => #<User id: 1, <snip>, created_at: "2011-11-25 22:01:46",
    updated_at: "2011-12-16 15:33:24", approved: true>
    ruby-1.8.7-p302 > u.created_at.day
    => 25

    Time and Date are quite different. Think seriously on your business need
    what
    you really need, a Time or a Date.

    if you need a _date_ e.g. start_date of a contract, don't use Time, it will
    get
    confusing when local time gets involved. The concept of

    contract_start_date => "1 Feb 2012"

    is different from the concept of

    contract_start_time => "1 Feb 2012 00:00:00+00"

    At contract_start_time (midnight in London) it is still 31 Jan 2011 7pm in
    NYC
    and the contract has _not_ started yet to NY standards ...

    HTH,

    Peter
